【Abstract】 Recently, pyroelectric IR sensor has received a great deal of attention in IR imaging field, because of its broad spectrum response and uncooling properties. A critical component in the pyroelectric IR sensor is the sense organ, which consists of the ferroelectric thin film in a certain shape and its up-down electrodes. In this paper, the preparation, structure and electric properties of the sensor materials were studied. Through semiconductor lithograph arts, the ferroelectric thin films was micropattered successfully by the chemical etch and the electrodes were shaped by lift-off techniques.This study is very important for the application of ferroelectric thin films in IR sensor.更多还原
